Show HN: Agents infer Lego mechanisms from sources, then animate them
Hi there :)
Around a month ago, I released LDraw Nova, an agentic toolset for assembling LEGO CAD models by generating LDraw source code files.
For more details, here's the Show HN post:

From the comments, I got the impression that there was quite an interest in seeing not only AI-generated LEGO models, but also AI-animated LEGO ones.
I took a look at results from past experiments, and found it feasible to use agentic LLMs for:
- analyzing the LDraw source code for LEGO models - reverse-engineer! the mechanisms present by reading the descriptions and sequence for the parts there - and then, animate them via Blender!
This new project I'm presenting, LDraw Mecha, is the end result and proof that can be done:
- Read specially annotated LDraw LEGO models .mpd source files - Infer the model structure in terms of submodels - Select from those the ones that are mechanisms - Plan animations - Execute them in Blender
In summary, from an initial .mpd source file, get a rigged and animated version for the model as a Blender (.blend) file.
See the results here:
- Repo (v0.5.0): https://github.com/anteloc/ldraw-mecha/tree/v0.5.0 - Gallery: https://github.com/anteloc/ldraw-mecha/blob/v0.5.0/GALLERY.m... - Process: https://github.com/anteloc/ldraw-mecha/blob/v0.5.0/PROCESS.m...
This project is very unusual, I'd really appreciate some feedback from the community.
Cheers!

DraftKings stock is collapsing: Why shares of the sports-betting app are in retreat today
Sports-betting app DraftKings is not on track to have as good a year as it once expected; the company trimmed its 2026 financial outlook amid the rise of competing prediction markets.
The company’s third-quarter earnings report released on November 5 showed projected full-year revenue of $6.35 billion to $6.55 billion, down from its previous estimates of $6.5 billion to $6.9 billion.
A day following the earnings report, DraftKings (Nasdaq: DKNG) saw its shares fall 23.6% to $17.9 at the time of publishing, reaching its lowest price in the last six months.
The stock is now down more than 49% year to date.
What are the odds?DraftKings’s lower outlook reflects the sports-betting company’s increased investment in the prediction sector of its business, the company said, with around $650 million to $700 million invested.
These prediction investments will not have revenue reflected in this year’s figures, the report said, as “new customer promotions will offset the lion’s share of gross revenue generated.”
The significant investment comes as prediction markets like Kalshi and Polymarket continue to gain ground in the U.S., allowing for users to wager money on real-life events like political elections or a TV show’s finale.
In its 2027 outlook, DraftKings forecasts a range of $7.35 billion to $7.75 billion in revenue, and $800 million to $1 billion in earnings before interest, taxes, depreciation, and amortization.
The revenue forecast contrasts with analyst projections of $7.6 billion, per consensus estimates cited by The Wall Street Journal.
As for the returns from the predictions investments, the 2027 guidance says the company is expecting around $650 million to $750 million in revenue.
“The third quarter marked a pivotal moment for DraftKings, as the Predictions offering we have been building is now powering meaningful growth for our business,” cofounder and CEO Jason Robins said in the report.
He added, “More than 1.6 million customers have engaged with Predictions year-to-date, and combined with the strength of our core, we believe we are set up for an exceptional 2027.”

Incoming Democratic senators don’t want Chuck Schumer as majority leader
New lawmakers from Annie Andrews and Adam Hamilton to Abdul El-Sayed indicate they will not support him
Incoming Democratic senators want someone other than Chuck Schumer to become the next majority leader in the US Senate, although Schumer likely still has enough votes in his caucus to remain the top Democrat.
Annie Andrews, the Democratic senator-elect from South Carolina, told Fox News’s Bret Baier on Thursday that the Democratic party needs new leadership. When asked whether she would support Schumer’s leadership bid, she replied: “I still very much believe it’s time for generational change on both sides of the aisle.”
